Neurogenic Orthostatic Hypotension. Lessons From Synucleinopathies. [PDF]
Am J Hypertens, 2021 Abstract Maintenance of upright blood pressure critically depends on the autonomic nervous system and its failure leads to neurogenic orthostatic hypotension (NOH). The most severe cases are seen in neurodegenerative disorders caused by abnormal α-synuclein deposits: multiple system atrophy (MSA), Parkinson’s disease, Lewy body dementia,

Norepinephrine reuptake blockade to treat neurogenic orthostatic hypotension. [PDF]
Clin Auton Res, 2021 <jats:title>Abstract</jats:title><jats:p>GNSS satellite and receiving antennas exhibit group delay variations (GDV), which affect code pseudorange measurements. Like antenna phase center variations, which affect phase measurements, they are frequency-dependent and vary with the direction of the transmitted and received signal.

Primary neurogenic orthostatic hypotension [PDF]
Journal of Neurology, Neurosurgery & Psychiatry, 1970 Eight further cases of neurogenic orthostatic hypotension are described together with a necropsy study on one case. Three cases showed evidence of autonomic dysfunction in isolation, while in five cases this was accompanied by evidence of more diffuse central nervous system degeneration.

Orthostatic hypotension: An overlooked but clinically decisive entity
Journal of the Indian Academy of Geriatrics, 2022 Orthostatic hypotension (OH) is defined as a drop of >20 mm Hg of systolic or >10 mm Hg of diastolic blood pressure (BP) within 3 min of standing from lying position. It is a common geriatric syndrome caused by impaired orthostatic response of BP.

Neurogenic Orthostatic Hypotension [PDF]
Circulation, 2009 Orthostatic hypotension (OH) is defined as a persistent, consistent, orthostatic fall in systolic blood pressure of ≥20 mm Hg or diastolic pressure of ≥10 mm Hg by 3 minutes of standing up.1 Acute, unexpected, episodic falls in blood pressure while standing, as in neurocardiogenic syncope, do not satisfy criteria for OH.

Droxidopa in neurogenic orthostatic hypotension [PDF]
Expert Review of Cardiovascular Therapy, 2015 Neurogenic orthostatic hypotension (nOH) is a fall in blood pressure (BP) on standing due to reduced norepinephrine release from sympathetic nerve terminals. nOH is a feature of several neurological disorders that affect the autonomic nervous system, most notably Parkinson disease (PD), multiple system atrophy (MSA), pure autonomic failure (PAF), and ...

Orthostatic hypotension and novel blood pressure-associated gene variants: Genetics of Postural Hemodynamics (GPH) Consortium [PDF]
, 2012 Aims: Orthostatic hypotension (OH), an independent predictor of mortality and cardiovascular events, strongly correlates with hypertension. Recent genome-wide studies have identified new loci influencing blood pressure (BP) in populations, but their ...

BMC Cardiovascular Disorders, 2020 Background Neurogenic orthostatic hypotension, a sustained decrease in blood pressure upon standing, is caused by autonomic nervous system failure and characterized by an insufficient increase in heart rate needed to maintain blood pressure upon standing.
